The input unit 110 includes a first panel 111, and a second panel 112, each having various keys.

In more detail, the first panel 111 is provided with keys for applying the cooking order to the microwave oven unit. The user applies the cooking order to the microwave oven to the control unit 120 through the keys on the first panel 111. The keys on the first panel 111 have orders given thereto according to cooking conditions in advance, for the user to press the keys on the first panel 111, to cook the food as the user desires.

The second panel 112 has keys for applying the coffee extracting order to the coffee maker unit. The user applies the coffee extracting order for the coffee maker unit to the control unit 120 through the keys on the second panel 112. The keys on the second panel 112 have the coffee extraction order given thereto in advance, and orders for selecting kinds of coffee may be given thereto in advance. By pressing the key on the second panel 112, the user can apply an order to extract a kind of coffee the user desires.

In the meantime, the input unit 110 further includes an enter key 113. The enter key 113 informs completion of application of orders to the control unit 120. The enter key 113 is a key the user orders the control unit 120 to carry out applied orders.

In more detail, upon completion of application of orders, the user presses the enter key 113. Then, the enter key 113 issues a signal, and the control unit 120 detects the signal, determines that application of order is completed, and carries out the orders.

That is, the coffee maker and microwave oven 100 is not put into operation until the user presses the enter key 113 after the user applies orders through the first panel 111 or the second panel 112.

In the meantime, the control unit 120 is provided to one side of the coffee maker and microwave oven 100. The control unit 120 carries out applied order thus, and provides food or coffee in a state the user desires. The control unit 120 controls the magnetron 21, and the high voltage transformer 22, and so on, to carry out the cooking order, or the water supply valve 39, and so on, to carry out the coffee extraction order.

In this instance, if the user applies the cooking order, or the coffee extraction order, the control unit 120 carries out the order the user applies, and provides cooked food or coffee. If the user applies both orders, the control unit 120 carries out the coffee extraction and the cooking in succession according to an order of application of the orders.

In the meantime, a method for controlling a coffee maker and microwave oven 100 in accordance with a second preferred embodiment of the present invention will be described with reference to FIG. 4.

One of a coffee extraction order for a coffee maker unit and a cooking order for a microwave oven unit is applied to a control unit 120 through an input unit 110 (S100). Then, the control unit 120 receives, and stores the order in a memory (not shown) therein (S200).

Then, the control unit 120 determines whether the user finishes application of order, or has additional order to apply (S300). In more detail, the control unit 120 determines that the user has additional order to apply when an order has applied to the first panel 111 or the second panel 112 of the input unit 110. The control unit 120 determines that application of order from the user is finished when an order is applied through the enter key 113.

Upon completion of application of the order, the control unit 120 carries out the stored orders (S400).

On the other hand, if there is an additional order received at the control unit, the first step is repeated.

When the first step is repeated, the control unit 120 stores the order applied thereto repetition next to the order applied at first. That is, the control unit 120 stores the orders in an order of application. In the fourth step, the control unit 120 carries out the stored orders in an order of storage.

The control method will be described, taking an example.

The user applies the coffee extraction order to the input unit 110. Then, the control unit 120 detects the coffee extraction order, and stores the coffee extraction order in the memory (not shown).

Then, the control unit 120 determines whether the user finishes application of order, or has an additional order to apply. If the user finishes application of order, the control unit 120 carries out the coffee extraction order.

However, if the user does not finish application of order, but applies a cooking order additionally, the control unit 120 detects the cooking order, and stores the cooking order in the memory (not shown). In this instance, the control unit 120 stores the cooking order next to the coffee extraction order stored already.

Then, the control unit 120 determines whether the user finishes application of order, or has an additional order to apply. If the user finishes application of order, the control unit 120 carries out the coffee extraction order at first, and the cooking order according to the order of storage.

In the meantime, FIG. 5 illustrates a flow chart showing the steps of another method for controlling a coffee maker and microwave oven in accordance with a second preferred embodiment of the present invention. The another method for controlling a coffee maker and microwave oven 100 in accordance with a second preferred embodiment of the present invention will be described with reference to FIG. 5.

The control unit 120 determines whether both a coffee extraction order for a coffee maker unit and a cooking order for a microwave oven are applied or not (S150).

If applied, the control unit 120 stores the order in a memory (not shown) according to an order of application (S250). Then, the control unit 120 carries out the stored orders according to an order of storage (S400).

In the meantime, after the S250, the control unit 120 detects whether a signal is issued from the enter key 113, or not. When the enter key 113 issues the signal, the control unit 120 carries out the S400. However, if the enter key 113 does not issue the signal, the control unit 120 terminates working (S350).

If only one order is applied in the S150, the control unit 120 does not store the order, but carries out the order. In this instance, the control unit 120 carries out the order when the signal is issued from the enter key 113. That is, the control unit 120 carries out the one order applied thereto, when the user finishes application of the order.

A coffee maker and microwave oven and a method for controlling the same in accordance with a third preferred embodiment of the present invention will be described, with reference to FIGS. 6 and 7.

The coffee maker and microwave oven in accordance with a third preferred embodiment of the present invention includes an input unit 110, and a control unit 120. The input unit 110 includes a first panel 111, and a second panel 112. The input unit 110 further includes an enter key 113.

The first panel 111, the second panel 112, the enter key, and the control unit 120 have functions the same with the description given in the second embodiment, and detailed description of which will be omitted, for avoiding repetition.

In the meantime, the input unit 110 further includes a control key 114. The control key 114 has a function for applying a preliminary order. The preliminary order is a function for informing successive application of a cooking order and a coffee extraction order to the control unit 120. Therefore, for successive application of a cooking order and a coffee extraction order, after pressing the control key 114, the user applies the order to the first panel 111 and the second panel 112.

A method for controlling a coffee maker and microwave oven 100 in accordance with a third preferred embodiment of the present invention will be described, with reference to FIG. 7.

The control unit 120 detects whether the control key 114 issues a signal, or not. That is, the control unit determines whether the user applies the preliminary order or not. Upon detecting the signal from the control key 114, the control unit 120 determines that both the cooking order and the coffee extraction order are received, and carries out the next step (S50).

The control unit 120 determines whether both the coffee extraction order for the coffee maker and the cooking order for the microwave oven are received or not (S150).

If received, the control unit 120 stores the orders in a memory (not shown) according to an order of reception (S250).

Then, the control unit 120 carries out the stored orders according to an order of storage (S400).

In the meantime, after S250, the control unit 120 detects whether the enter key 113 issues a signal or not. If the enter key 113 have issued the signal, the control unit 120 carries out S400. However, if the enter key 113 does not issue the signal, the control unit 120 terminates working (S350).

If only one order is received in S150, the control unit 120 does not store the order, but carries out the order when the signal is issued from the enter key 113. That is, when the user finishes application of an order, the control unit 120 carries out the order received.

In the meantime, if order are received without the control key 114 is not pressed in the step S50, the control unit 120 detects the order. Then, when the enter key 113 issues the signal, the control unit 120 carries out the order. That is, when the user finishes application of an order, the control unit 120 carries out the order received.

Though not shown, in a case two orders are received without the control key 114 being pressed, of the order, the control unit 120 carries out the order received at first.

As has been described, the coffee maker and microwave oven, and a method for controlling the same of the present invention is convenient to use because a cooking order for the microwave oven unit and a coffee extraction order for the coffee maker unit can be carried in succession.
